DISASSEMBLY
WARNING
Death or personal injury may result from explosion of fuel fumes exposed to an
open flame or spark or to static discharge. Do not permit smoking, any open flame
or spark producing equipment within fifty feet of the repair location.
Rubber gloves should be worn when handling nozzle parts due to toxic effects of
some fuel additives.
Piston assembly is under an initial spring load of approximately 65 psi. Use care in
disassembly to avoid serious injury to personnel and equipment.
NOTE
Disassemble equipment only to the extent necessary for repair.
1.
Depress piston assembly [outer piston (1), screw (2), Stat-O-Seal (3) and inner piston (4)], using an arbor press, drill
press or equivalent and remove retaining ring (5) from housing (6).
2.
Slowly release load from arbor press, allowing the piston spring (7) to push the piston assembly out of housing (6).
Remove piston assembly and piston spring (7).
NOTE
It is not necessary to separate the piston assembly parts unless replacing part(s). If
disassembly is required, continue with step 3, otherwise go to step 4.
